The 51 mm version is the one with the famous 27-day/78 h numbers — the 47 mm reviewed here is roughly half that. | Suunto does not publish a separate always-on smartwatch number; DC Rainmaker measured about 50 h of real use with dual-frequency, always-on display and navigation all running against a 65 h claim |
| Battery, Single-Band GPS ( h) | 44 | 75✓ |
| Battery, Multiband GPS ( h) | 30 | 65✓ |
| GNSS Bands | Multi-band L1+L5 (GPS, GLONASS, Galileo, BeiDou, QZSS) with SatIQ | Dual-band L1+L5 Sony chipset. Four published tiers: 65 h Performance (dual-band), 75 h Endurance (single-band all systems), 110 h Ultra (single-band, wrist HR off) and 250 h Tour (GPS only, 2-minute logging). |

| Training Platform & Subscription | Garmin Connect is free and every core training metric — Training Readiness, Training Load, Training Status, HRV Status, Body Battery, recovery time — is Firstbeat-derived and free on the watch (Garmin bought Firstbeat in 2020). Connect+ is $6.99/mo or $69.99/yr and adds only AI wellness prompts, 3D maps, Trails+ routing, extra badges and nutrition logging — nothing a training plan depends on. Separately, the satellite and LTE features are useless without a Garmin subscription: US plans run $7.99/mo (10 satellite messages) to $29.99/mo (unlimited) — a recurring cost on a $1,199.99 watch. | Suunto app is free with no subscription tier; analytics are Suunto's own |
